HEK293 Cells

A DNA sequence encoding the extracellular domain (Met1-Thr652) of human ERBB2 (NP_004439.2) was expressed with a C-terminal polyhistidine tag. The protein is site-specifically conjugated with AF 488 (Excitation Max.= 495 nm, Emission Max.= 519 nm).

≥ 90% as determined by SDS-PAGE.

Please refer to the lot-specific COA.

Twelve months from date of receipt at -20℃ to -70℃ in lyophilized form and 3 months at -70℃ under sterile conditions after reconstitution. Protect from prolonged exposure to light and avoid repeated freeze-thaw cycles.

Human epidermal growth factor receptor 2 (HER2), also known as ErbB2, NEU, and CD340, is a type I membrane glycoprotein and belongs to the epidermal growth factor (EGF) receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
